Mites parasitic on spiders, with a description of a new species of Eutrombidium (Acari, Eutrombidiidae)

A new species of Eutrombidium is described from larvae parasitizing 38 Ceraticelus emertoni (O. Pickard-Cambridge) (Araneae, Linyphiidae) and one Oxyopes salticus Hentz (Araneae, Oxyopidae) collected in Mississippi. Most host individuals (89%) were parasitized by only one larva, but as many as nine...

Description
Summary:A new species of Eutrombidium is described from larvae parasitizing 38 Ceraticelus emertoni (O. Pickard-Cambridge) (Araneae, Linyphiidae) and one Oxyopes salticus Hentz (Araneae, Oxyopidae) collected in Mississippi. Most host individuals (89%) were parasitized by only one larva, but as many as nine larvae were attached to one host. Adult and immature hosts of both sexes were parasitized. All larval mites were attached to the lateral molt sutures, mostly on the posterior prosoma. A review of the literature reveals 30 records of mite ectoparasitism of spiders among eight mite genera from five continents. Six additional records are reported herein. Two species listed as spider parasites, Allothrombium metae Boshell & Kerr (Acari, Trombidiidae) and Copriphis bristowi Finnegan (Acari, Laelapidae), are transferred to Clinotrombium and Ljunghia, respectively.
